Add specific calibration for 2nd orientation sensor

I created a adamgreenBlack.config specifically for tracking the
calibration data for the second black unit.
Initial commit of simple blob detection sample

This is a simple colour blob detector written in Processing.  Features
include:
* It shows two images side by side.  The left image is the live video
  feed from the camera and the right image is a snapshot taken from the
  video feed.
* Pressing the <space> key will populate the snapshot image.
* Bright yellow pixels in the live video indicate pixels which match
  the current colour blob constraints.  It draws a rectangle around the
  area containing all such pixels.
* There are two to three columns of numbers at the bottom.
* The first two columns are always displayed.
* The first column displays the hue, saturation, and brightness value
  being used for the blob detection constraints.
* The second columns displays the threshold constraints for the hue,
  saturation, and brightness.  Pixels which have colour channel values
  that differ by less than or equal to this threshold will be
  considered matching.  The smaller the threshold value, the more
  restrictive the match.
* The boxes next to the threshold values are crude buttons that can be
  pressed to increase or decrease their corresponding threshold value.
* The second column displays another threshold.  This is the floating
  point distance threshold used during flood fill.
* The user can move the mouse over pixels in the snapshot image and
  press the mouse button to perform a flood fill from that pixel.  It
  will match pixels that differ by no more than the fill threshold
  amount.  The floodfill will use the filled pixels to update the
  blob detection constraints.  This sets the blob detector to detect
  pixels which are similar to the object containing the selected pixel.
  The flooded pixels will be highlighted as bright yellow for two
  seconds and then return to showing the original snapshotted image.
* The third column of values only shows up at the bottom when the user
  hovers the mouse over pixels in the snapshot image.  It shows the
  hue, saturation, and brightness of the currently selected pixel.

I have included an example adamgreen.config file which defaults the
blob detection constraints and tells the sample to use the front facing
FaceTime camera on my MacBook Air at 640 x 360 resolution.

I will update this sample in the near future to return more than 1
blob.  If there are multiple candidate objects in the image, it will
return a bounding box for each instead of one large box to encompass
them all.

I also need to add support for other camera resolutions.  Some parts of
the code are hardcoded to 640 x 360 but they don't need to be.
